How carboniferous limestone is formed?

Carboniferous Limestone is a sedimentary rock made of calcium carbonate. It is generally light-grey in colour, and is hard. It was formed in warm, shallow tropical seas teeming with life. The rock is made up of the shells and hard parts of millions of sea creatures, some up to 30 cm in length, encased in carbonate mud.
A.

How limestone is formed for kids?

Limestone is a type of rock that is made up of bits of animal shells. Over millions of years these shells collected on the ocean floor. As layers of shells and mud built up, the lower layers slowly hardened into limestone. Dover, England, is famous for its white cliffs made of chalk, a soft form of limestone.
  • How is a limestone formed?

    Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris.
  • How is limestone used?

    It is the raw material for the manufacture of quicklime (calcium oxide), slaked lime (calcium hydroxide), cement and mortar. Pulverized limestone is used as a soil conditioner to neutralize acidic soils (agricultural lime). Is crushed for use as aggregate—the solid base for many roads as well as in asphalt concrete.
  • What is the color of limestone?

    Limestones are shades of bluish gray to tan. The brown and yellow shades are usually caused by iron oxide impurities and the dark-gray to black colors are caused by organic material. The texture of limestone ranges from coarsely crystalline to very fine grained.
B.

What is limestone made out of?

Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3). It often has variable amounts of silica in it, as well as varying amounts of clay, silt, and sand. Limestone rocks fall under the category of sedimentary rocks that are made from mineral calcite.
  • Where does the lime come from?

    Limes are grown on trees that flourish in tropical and subtropical climates. They were thought to originate in Southeast Asia. Arab traders brought lime trees back from their journey to Asia and introduced them into Egypt and Northern Africa around the 10th century.
  • Is lime dust bad for you?

    Lime, particularly quicklime, is an alkaline material that is reactive in the presence of moisture. Workers handling lime must be trained and wear proper protective equipment. Eye HazardsLime can cause severe eye irritation or burning, including permanent damage. Inhalation HazardsLime dust is irritating if inhaled.
  • Is a lime a lemon?

    If Limes are allowed to fully ripen on the tree, they actually turn from green to yellow. Because of this, some people believe (erroneously) that Limes are just unripe Lemons. Whereas, truth to tell, even the Lemons that we buy are unripe Lemons. Limes have more sugar and citric acid than do lemons.
C.

How a limestone pavement is formed?

Formation of a limestone pavement. Limestone is slightly soluble in water and especially in acid rain, so corrosive drainage along joints and cracks in the limestone can produce slabs called clints isolated by deep fissures called grikes or grykes (terms derived from a northern English dialect).
  • How many steps are there at Malham Cove?

    On the west side of the 80 metre (260 foot) high cliff face are about 400 irregular stone steps: these form part of the route of the Pennine Way and lead to an uneven limestone pavement at the top.
  • What is a karst landscape?

    Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. Subterranean drainage may limit surface water, with few to no rivers or lakes.
  • What is the difference between a Clint and a Grike?

    Pavements are made up of two separate but integral parts known as clints and grykes. Clints are the blocks of limestone that constitute the paving, their area and shape is directly dependant upon the frequency and pattern of grykes. Grykes are the fissures that isolate the individual clints.
